Multicast Switch
![MCS MCS](https://resource.lumentum.com/s3fs-public/main-images/mcs_34564k16-lumentum-web.png)
Multicast switches are wavelength insensitive (and thus transmission speed independent) optical switches which can connect any number of optical inputs and outputs in a fully non-blocking non-restrictive way. This functionality is built using a large array of optical power splitters interconnected to a large array of optical switches. N 1xM splitters connected to M 1xN switches form an NxM multicast switch. A typical MCS configuration is 8x16, however both smaller and larger port-count product versions are also available.
